Safety conditions
PRECAUTIONS AGAINST PRODUCT DAMAGE
• Work environment.
This unit is ready to be used in industrial environments complying with the directives and regulations
effective in the European Community.
Fagor Automation shall not be held responsible for any damage that could suffer or cause when installed
under other conditions (residential or domestic environments).
• Install this unit in the proper place.
It is recommended, whenever possible, to install the CNC away from coolants, chemical product, blows,
etc. that could damage it.
This unit meets the European directives on electromagnetic compatibility. Nevertheless, it is
recommended to keep it away from sources of electromagnetic disturbance, such as:

Powerful loads connected to the same mains as the unit.

Nearby portable transmitters (radio-telephones, Ham radio transmitters).

Nearby radio / TC transmitters.

Nearby arc welding machines.

Nearby high voltage lines.

Etc.
• Enclosures.
It is up to the manufacturer to guarantee that the enclosure where the unit has been installed meets
all the relevant directives of the European Union.
• Avoid disturbances coming from the machine tool.
The machine-tool must have all the interference generating elements (relay coils, contactors, motors,
etc.) uncoupled.

DC relay coils. Diode type 1N4000.

AC relay coils. RC connected as close to the coils as possible with approximate values of R=220

1 W y C=0,2 µF / 600 V.

AC motors. RC connected between phases, with values of R=300

/ 6 W y C=0,47 µF / 600 V.
• Use the proper power supply.
Use an external regulated 24 Vdc power supply for the inputs and outputs.
• Connecting the power supply to ground.
The zero Volt point of the external power supply must be connected to the main ground point of the
machine.
• Analog inputs and outputs connection.
It is recommended to connect them using shielded cables and connecting their shields (mesh) to the
corresponding pin.
• Ambient conditions.
The working temperature must be b5 ºC and +40 ºC (41ºF and 104º F)
The storage temperature must be between -25 ºC and +70 ºC. (-13 ºF and 158 ºF)
• Monitor enclosure (CNC 8055) or central unit ( CNC 8055i)
Guarantee the required gaps between the monitor or the central unit and each wall of the enclosure.
Use a DC fan to improve enclosure ventilation.
• Power switch.
This power switch must be mounted in such a way that it is easily accessed and at a distance between
0.7 meters (27.5 inches) and 1.7 meters (5.5ft) off the floor.
